Instant noddles and method for producing instant noddles

ABSTRACT

The present invention provides instant noodles containing agar and curdlan, having water absorption of 250% or more upon reconstitution with water at 20° C. for 3 minutes, and being capable of reconstitution with water in a time of 5 minutes or less, and having an excellent texture with suitable hardness.

TECHNICAL FIELD

The present invention relates to instant noodles and a method for producing the instant noodles.

BACKGROUND ART

When conventional instant noodles are to be eaten, noodle masses made of wheat flour, starch or buckwheat flour as a main raw material are packed in a container, for example, together with soup and other ingredients, and after pouring hot water thereto, the noodle masses are reconstituted with the hot water usually for 3 to 5 minutes before eating.

In such instant noodles, various modifiers are added for improving the texture, etc. of the noodles. For example, Jpn. Pat. Appln. KOKAI Publication No. 2-97361 describes that the texture of noodles produced in a usual manner from wheat flour or buckwheat flour as a main raw material can be improved by using thickening natural polysaccharides such as curdlan and guar gum as quality improvers in a part of starting materials to be added.

From the viewpoint of diversification and simplification of food, there has been demand for noodles eatable by reconstitution with water at room temperature (ordinary temperature) at about 20° C. in place of hot water. However, instant noodles that can be delectably eaten by reconstitution with water at room temperature in a short time of 3 to 5 minutes have not been known at all. For example, Jpn. Pat. Appln. KOKAI Publication No. 10-136949 describes a dried product of agar eatable by reconstitution with water, which is in a form shrunk amorphously by drying, under rotation or rolling, an agar gel that was cut in a suitable shape and size.

The dried product of agar described in Jpn. Pat. Appln. KOKAI Publication No. 10-136949 is, however, composed of agar, thus requiring considerable time on reconstitution with water, and has a very hard texture that is not suitable for eating upon reconstitution with water for 5 minutes or so.

BEST MODE FOR CARRYING OUT THE INVENTION First Embodiment

The instant noodles in a first embodiment contain agar and curdlan and have water absorption of 250% or more upon reconstitution with water at 20° C. for 3 minutes.

When instant noodles consist of the agar and the curdlan, the agar and the curdlan are compounded preferably in ratios of 1 to 90% by weight and 10 to 99% by weight, respectively. When the compounding ratio of the curdlan is lower than 10% by weight, the time for reconstitution with water may be prolonged and the noodles after reconstitution with water may have become hard. On the other hand, when the compounding ratio of the curdlan is higher than 99% by weight, the texture of the noodles after reconstitution with water may be deteriorated. The compounding ratios of the agar and the curdlan are more preferably 8 to 75% by weight and 25 to 92% by weight, respectively.

It is allowable that the instant noodles in the first embodiment are further compounded a third component of at least one selected from wheat flour and starch. Examples of wheat flour that can be used herein include strong wheat flour, medium wheat flour and weak wheat flour. These wheat flours may be used alone or as a mixture of two or more thereof. Examples of starches that can be used herein include potato starch, corn starch, wheat starch, and tapioca starch.

The third component is incorporated in a ratio of preferably 80% by weight or less, more preferably 70% by weight or less, based on the total amount of the agar and the curdlan. When the compounding ratio of the third component is higher than 80% by weight, water reconstitution in a short time (for example 3 minutes or so) becomes difficult.

The water absorption refers to a value (%) determined by using the equation: (w1/w0)×100 wherein w1 is the weight of noodles that are reconstituted with water and w0 is the weight of the noodles before reconstitution.

In the first embodiment, the water absorption (250% or more) of the instant noodles upon reconstitution with water at 20° C. for 3 minutes indicates a specific property of the instant noodles, and the water absorption of the instant noodles, even if the third component is contained in its compounding upper limit (i.e. 80% by weight), is 250% or more upon reconstitution with water at 20° C. for 3 minutes. However, when the instant noodles are composed of the agar and the curdlan, the water absorption thereof is preferably 400% or more upon reconstitution with water at 20° C. for 3 minutes.

It is allowable that the instant noodles in the first embodiment have a multilayer structure such as a 3-, 4- or 5-layer structure. The instant noodles having such a multilayer structure comprises outer layers contained the agar and the curdlan. An inner layer positioned between the outer layers has a composition different from that of the outer layers. Even in the instant noodles having such a multilayer structure, the water absorption thereof is 250% or more upon reconstitution with water at 20° C. for 3 minutes.

When the outer layer in the instant noodles of multilayer structure is composed of agar and curdlan, the agar and curdlan are incorporated preferably in ratios of 10 to 80% by weight and 20 to 90% by weight, respectively.

It is allowable that in the instant noodles of multilayer structure, the inner layer contains at least one component selected from agar and curdlan, or contains at least one component selected from polysaccharides and proteins. Particularly, the inner layer more preferably contains at least curdlan in consideration of water reconstitution.

It is allowable that in the instant noodles of multilayer structure, the outer layer and inner layer are further compounded respectively with at least one material as a third component selected from the above-mentioned wheat flour and starch.

The third component is incorporated preferably in a ratio of 80% by weight or less, more preferably 70% by weight or less, based on the total amount of the agar and the curdlan in the multilayer structure. When the compounding ratio of the third component is higher than 80% by weight, water reconstitution in a short time (for example 3 minutes or so) becomes difficult. The third component is incorporated preferably in a weight ratio of 0:100 to 80:20 in the outer layer:inner layer.

It is allowable that in the instant noodles in the first embodiment, various additives such as salts (e.g., sodium and potassium salts), amino acids, vitamins, and other food materials are added depending on the type of the noodles.

When the instant noodles in the first embodiment are to be eaten, the instant noodles may be reconstituted with water at 20° C. or less, for example cold water at about 4° C., without limitation to reconstitution with water at 20° C.

Hereinafter, a method for producing the instant noodles of a monolayer structure mentioned above will be described.

i) A sol of raw material containing agar and curdlan is prepared.

Specific preparation of the sol includes the following three methods:

(a) Agar is dispersed in water and dissolved by heating at 80 to 100° C. for example. A dispersion of curdlan in water is added to this heated aqueous solution of the agar while the temperature drops for example to 60° C., thereby preparing the sol.

(b) A dispersion of curdlan in water is heated for example from 40 to 60° C. In this heating process, the dispersion of the curdlan in water is converted into sol. When the temperature of this sol rises, for example, to 50° C., this temperature is maintained while a solution prepared by dissolving agar in heated water is added to the sol, to prepare the sol of raw material containing the agar and the curdlan.

(c) Agar is dispersed in water and dissolved by heating at 80 to 100° C., for example, and then gelatinized by cooling. The gel is milled to form the agar in sol form. This agar in sol form is added to a dispersion of curdlan in water, to prepare the sol of raw material containing the agar and the curdlan.

The total concentration of the agar and the curdlan in the sol is preferably 0.2 to 6.0% by weight. When the total concentration in the sol is lower than 0.2% by weight, gelatinizing, described later, may be difficult. On the other hand, when the total concentration in the sol is higher than 6.0% by weight, the resulting noodles may not be reconstituted with water in a short time (for example, about 3 minutes). The total concentration of the agar and the curdlan in the sol is more preferably 1.0 to 5.0% by weight.

The agar and the curdlan are compounded preferably in a weight ratio of from 1:99 to 90:10 in the sol, respectively. When the content ratio of the curdlan is lower than 10, the time for reconstituting the resulting instant noodles with water may be prolonged, and the noodles after reconstitution with water may become too hard. On the other hand, when the content ratio of the curdlan is higher than 99, the texture of the noodles after reconstitution with water may be deteriorated. The ratio of the agar and the curdlan is more preferably from 8:92 to 75:25 by weight.

It is allowable that a third component of at least one selected from wheat flour and starch is further contained in the sol. As the wheat flour, any of strong wheat flour, medium wheat flour and weak wheat flour for example may be used. These wheat flours may be used singly or as a mixture of two or more thereof. As the starch, any of potato starch, corn starch, wheat starch and tapioca starch for example may be used. The third component is incorporated in a ratio of preferably 80% by weight or less, more preferably 70% by weight or less, based on the total amount of the agar and the curdlan.

It is allowable that, depending on the type of instant noodles to be produced, various additives such as salts (e.g., sodium and potassium salts), amino acids, vitamins, and other food materials are further added to the sol.

ii) Gelled noodle strings are formed from the sol.

In preparation of gelatinized noodle strings from the sol, the following methods are used.

(1) The sol is spread on a plate made of glass or a metal such as stainless steel to form a sheet and then gelatinize by cooling the sheet to form a gelatinized noodle strip, and this gelatinized noodle strip is dried if necessary and then cut thin thereby preparing gelatinized noodle strings.

Cooling for gelatinizing is conducted for example at a temperature of preferably 20° C. or less, more preferably 0 to 10° C.

(2) The sol is spread on a plate made of glass or a metal such as stainless steel to form a sheet and then gelatinized by heating the sheet to form a gelatinized noodle strip, and this gelatinized noodle strip is dried if necessary and then cut thin thereby preparing gelatinized noodle strings.

For example, the heating temperature is preferably 80 to 100° C.

For the heating, a steaming method may be used. In the case of heating by steaming, it is preferable that the sol is applied in the form of a sheet on a metal mesh such as a stainless steel mesh, and the sheet-like sol on the mesh is heated by steaming the surface thereof and the backside of the mesh.

(3) The sol is discharged directly from a tube or nozzles to form thin strings and then gelatinized by cooling or heating the thin strings to form gelatinized noodle strings.

The cooling is conducted, for example, at a temperature of preferably 20° C. or less, more preferably 0 to 10° C. The heating is conducted preferably at 80 to 100° C. for example, and treatment with a steamer can be used.

iii) The gelatinized noodle strings are dried to produce instant noodles.

Specifically, the gelatinized noodle strings are dried and placed in a one-meal-size treatment container (for example, a retainer) and dried to prepare noodle masses. For example, the noodle masses are thereafter placed in a cup and sealed to produce cupped instant noodles. Other ingredients and soup are also packed in the cup.

As described above, the instant noodles in the first embodiment are characterized by comprising agar and curdlan and having water absorption of 250% or more upon reconstitution with water at 20° C. for 3 minutes. That is, the hard texture of noodles produced from the agar alone is improved and the long time of reconstitution thereof with water is reduced by incorporating curdlan having a property of being excellently reconstituted with water, so that there can be provided instant noodles being capable of reconstitution with water at 20° C. in a short time of 3 minutes and having an excellent texture with suitable hardness.

Particularly, the instant noodles being capable of reconstitution with water in a short time and having a more excellent texture can be obtained by comprising agar and curdlan incorporated in ratios of 1 to 90% by weight and 10 to 99% by weight, respectively.

According to the first embodiment, a sol of raw material containing agar and curdlan is prepared, and gelatinized noodle strings are prepared from this sol and then dried, whereby instant noodles being capable of reconstitution with water at 20° C. in a short time of 3 minutes and having an excellent texture with suitable hardness can be produced.

Instant noodles being capable of further shortening the time of constitution with water and having a more excellent texture can be produced by allowing the total concentration of the agar and the curdlan in the sol to be 0.2 to 6.0% by weight.

Second Embodiment

The instant noodles in a second embodiment comprise carrageenin and curdlan and have water absorption of 300% or more upon reconstitution with water at 20° C. for 5 minutes.

As the carrageenin, κ-carrageenin for example can be used.

When instant noodles consist of carrageenin and curdlan, the carrageenin and the curdlan are compounded preferably in ratios of 2 to 98% by weight and 2 to 98% by weight, respectively. When the compounding ratio of the curdlan is lower than 2% by weight, the time for reconstitution with water may be prolonged and the noodles after reconstitution with water may become hard. On the other hand, when the compounding ratio of the curdlan is higher than 98% by weight, the texture of the noodles after reconstitution with water may be deteriorated. The compounding ratios of the carrageenin and the curdlan are 2 to 35% by weight and more preferably 65 to 98% by weight, respectively.

It is allowable that the instant noodles in the second embodiment, similar to those in the first embodiment, are further compounded a third component of at least one selected from wheat flour and starch. The third component is compounded preferably in a ratio of 60% by weight or less, more preferably 50% by weight or less, based on the total amount of the carrageenin and the curdlan. When the compounding ratio of the third component is higher than 60% by weight, gelatinizing may be difficult, the reconstitution of the resulting instant noodles with water may also be difficult, and the texture thereof may be deteriorated, particularly when wheat flour is used as the third component.

The water absorption (300% or more) of the instant noodles in the second embodiment upon reconstitution with water at 20° C. for 5 minutes indicates a specific property of the instant noodles, and the water absorption of the instant noodles, even if the third component is contained in its compounding upper limit (i.e. 60% by weight), is 300% or more upon reconstitution with water at 20° C. for 5 minutes. However, when the instant noodles consist of the carrageenin and the curdlan, the water absorption thereof is preferably 450% or more upon reconstitution with water at 20° C. for 5 minutes.

It is allowable that in the instant noodles in the second embodiment, various additives such as salts (e.g., sodium and potassium salts), amino acids, vitamins, and other food materials are further added depending on the type of the instant noodles.

When the instant noodles in the second embodiment are to be eaten, the instant noodles may be reconstituted with water at 20° C. or less, for example cold water at about 4° C., without limitation to reconstitution with water at 20° C.

Hereinafter, a method for producing the instant noodles described above will be explained.

i) A sol of raw material containing carrageenin and curdlan is prepared.

Specifically, the carrageenin and the curdlan are dispersed in water and heated, for example, at 40 to 50° C. to prepare a sol.

The total concentration of the carrageenin and the curdlan in the sol is preferably 1.2 to 7.2% by weight. When the total concentration in the sol is lower than 1.2% by weight, gelatinizing described later may be difficult. On the other hand, when the total concentration in the sol is higher than 7.2% by weight, the resulting instant noodles may not be reconstituted with water in a short time (for example about 5 minutes).

The Carrageenin and the curdlan are compounded preferably in a weight ratio of from 2:98 to 98:2. When the content ratio of the curdlan is lower than 2, the time for reconstituting the resulting instant noodles with water may be prolonged, and the noodles after reconstitution with water may become too hard. On the other hand, when the content ratio of the curdlan is higher than 98, the texture of the noodles after reconstitution with water may be deteriorated.

It is allowable that a third component of at least one selected from wheat flour and starch is further contained in the sol similar to that in the first embodiment described above. The third component is incorporated in a ratio of preferably 60% by weight or less, more preferably 50% by weight or less, based on the total amount of the carrageenin and the curdlan.

It is allowable that, depending on the type of instant noodles to be produced, various additives such as salts (e.g., sodium and potassium salts), amino acids, vitamins, and other food materials are further added to the sol.

ii) Gelled noodle strings are formed from the sol.

In preparation of gelatinized noodle strings from the sol, the following methods are used.

(1) The sol is spread on a plate made of glass or a metal such as stainless steel to form a sheet and then gelatinize by cooling the sheet to form a gelatinized noodle strip, and this gelatinized noodle strip is dried if necessary and then cut thin, thereby preparing gelatinized noodle strings.

Cooling for gelatinizing is conducted, for example, at a temperature of preferably 20° C. or less, more preferably 0 to 10° C.

(2) The sol is spread on a plate made of glass or a metal such as stainless steel to form a sheet and then gelatinize by heating the sheet to form a gelatinized noodle strip, and this gelatinized noodle strip is dried if necessary and then cut thin, thereby preparing gelatinized noodle strings.

For example, the heating temperature is preferably 80 to 100° C.

For heating, a steaming method may be used. In the case of heating by steaming, it is preferable that the sol is applied in the form of a sheet on a metal mesh such as a stainless steel mesh, and the sheet-like sol on the mesh is heated by steaming the surface thereof and the backside of the mesh.

(3) The sol is discharged directly from a tube or nozzles to form thin strings and then gelatinize by cooling or heating the thin strings to form gelatinized noodle strings.

Cooling is conducted for example at a temperature of preferably 20° C. or less, more preferably 0 to 10° C. Heating is conducted preferably at 80 to 100° C. for example, and treatment with a steamer can be used.

When the method of gelatinizing by cooling is used, the total concentration of the carrageenin and the curdlan in the sol is preferably 1.2 to 5.2% by weight, more preferably 1.5 to 5.0% by weight. At this time, the carrageenin and the curdlan in the sol are contained preferably in a weight ratio of from 2:98 to 98:2, more preferably in a weight ratio of from 2:98 to 35:65.

When the method of gelatinizing by heating is used, the total concentration of the carrageenin and the curdlan in the sol is preferably 2.2 to 7.2% by weight, more preferably 2.2 to 5.2% by weight. At this time, the carrageenin and the curdlan in the sol are compounded preferably in a weight ratio of from 2:98 to 98:2, more preferably in a weight ratio of from 2:98 to 35:65.

iii) The gelatinized noodle strings are dried to produce instant noodles.

Specifically, the gelatinized noodle strings are dried and placed in a one-meal-size treatment container (for example a retainer) and dried to prepare noodle masses. For example, the noodle masses are thereafter placed in a cup and sealed to produce cupped instant noodles. Other ingredients and soup are also packed in the cup.

As described above, the instant noodles in the second embodiment are characterized by comprising carrageenin and curdlan and having water absorption of 300% or more upon reconstitution with water at 20° C. for 5 minutes. That is, there can be provided instant noodles which, due to the interaction between the carrageenin and the curdlan, can be reconstituted with water at 20° C. in a short time of 5 minutes and have an excellent texture with suitable hardness.

Particularly, the instant noodles being capable of reconstitution with water in a short time and having a more excellent texture can be obtained by incorporating carrageenin and curdlan in ratios of 2 to 98% by weight and 2 to 98% by weight, respectively.

According to the second embodiment, a sol of raw material containing carrageenin and curdlan is prepared, and gelatinized noodle strings are prepared from this sol and then dried, whereby instant noodles being capable of reconstitution with water at 20° C. in a short time of 5 minutes and having an excellent texture with suitable hardness can be produced.

Particularly, when the sol is gelatinized by cooling such as in the method (1) above in preparation of gelatinized noodle strings, instant noodles being capable of reconstitution with water in a short time of 5 minutes and having a more excellent texture, due to the excellent water reconstitution of curdlan, can be produced by incorporating the carrageenin and the curdlan wherein the total concentration of the carrageenin and the curdlan in the sol is 1.2 to 5.2% by weight and simultaneously the weight ratio of carrageenin:curdlan in the sol is in a weight ratio of from 2:98 to 98:2.

When the sol is gelatinized by heating (for example, steaming) such as in the method (2) above in preparation of gelatinized noodle strings, instant noodles being capable of reconstitution with water in a short time (for example 5, minutes or so) and having a more excellent texture, due to the interaction between the carrageenin and the curdlan, can be produced by incorporating the carrageenin and the curdlan wherein the total concentration of the carrageenin and the curdlan in the sol is 2.2 to 7.2% by weight and simultaneously the weight ratio of the carrageenin the curdlan is in a weight ratio of from 2:98 to 98:2.

Hereinafter, Examples of the present invention will be described in detail. In the following Examples and Comparative Examples, the sol concentration value is shown by being rounded off the number to the first decimal place, and the water absorption is shown by being rounded off to the nearest one. The weight ratio of agar and curdlan in Tables 1 and 3 and the weight ratio of carrageenin and curdlan in Tables 2 and 4 are shown by being rounded to the integer decimal place, if those ratio values have only figures after decimal point.
